Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 128

A minimal faithful permutation representation — 6 generators on 28 points:

(6,9)(7,11)(14,17)(15,19)(21,22)(23,25)(24,27)(26,28);(13,14)(15,18)(16,17)(19,20)(21,23)(22,24)(25,28)(26,27);(6,9)(7,11)(23,27)(24,25);(2,4)(15,19)(18,20)(21,22)(23,24)(25,27)(26,28);(1,2)(3,4)(5,6)(7,10)(8,9)(11,12)(13,14)(15,18)(16,17)(19,20)(21,24,26,25)(22,27,28,23);(1,2)(3,4)(5,7,8,11)(6,10,9,12)(13,15)(14,18)(16,19)(17,20)(21,25,26,24)(22,23,28,27)

GAP

Past the SmallGroups library coverage — no SmallGroups id. Construct it from its polycyclic presentation:
